DETERMINATION OF PRINCIPAL REACTIONS IN 4:1 MIXTURES OF N2 AND O2 DURING CONTINUOUS IONIZATION

Computer solutions were obtained for 15 simultaneous differential equations which describe the time rate of change of electrons, NO2(-), O(-), O2(-), O3(-), N2(+), O(+), O2(+), NO(+), N, NO, N2O, NO2, O and O3 during continuous ionization. Initially 139 reactions involving these 15 species plus N2 a...

Description
Summary:Computer solutions were obtained for 15 simultaneous differential equations which describe the time rate of change of electrons, NO2(-), O(-), O2(-), O3(-), N2(+), O(+), O2(+), NO(+), N, NO, N2O, NO2, O and O3 during continuous ionization. Initially 139 reactions involving these 15 species plus N2 and O2 were considered using the computer code. The number of reactions was reduced to 35 without appreciably changing the solutions. Further reduction to 15 reactions gave orders of magnitude changes in the solutions. Reinsertion of three mutual neutralization reactions involving NO(+) gave solutions close to those obtained employing 35 reactions. The solutions reveal that the NO(+) and NO2(-) number densities become the largest of the positive ions and negative ions, respectively. The reaction sequences which lead to this result were determined. These sequences along with the neutral formation sequence are represented by schematic diagrams. (Author)
